Can The Cruze Pcv Valve Be Cleaned

This April, I finally caved and bought a fuel-mileage machine, a 2022 Chevrolet Cruze Eco. 1.4L turbo, 148 horsepower, twoscore MPG boilerplate with the air-conditioning on, wherever I become. Oh, and the six-speed…the entire reason I bought the automobile in the beginning identify. If I'm going to have a mileage car, I at to the lowest degree want to enjoy driving it. And to be honest, I learned to like this little black sedan quite a bit. It's quiet, information technology'due south adequately well equipped, and it runs well enough. Rather, it did…right upwards until mid-November. The first indication of trouble was easy enough to spot: oil vapor coming through the heater vent while heading into town. Next thing I know, the engine is venting oil out of the oil fill cap and is spraying information technology all over the engine bay. And it runs like hell, to kicking. After letting the dealership perform a once-over on the car to confirm a suspicion, I was offered up the chance to spend over seven hundred dollars to replace the intake manifold, because the cheque valve that resides in the center port had pulled a Houdini and had disappeared.

In the 3rd generation of the Opel-designedFamily 0 engine series, the turbocharged cars utilize an integrated check valve (in GM-speak, a non-return valve) that justvolition neglect at some indicate. In fact, information technology's one of two failure-prone valves…the other is at the turbo inlet. Now, to be articulate, upwardly until this incident, the Cruze'south issues had more to practice with age and clothing than anything else. I had replaced a leaking thermostat housing and the valve cover already (the PCV itself is an integral role of the valve encompass and cannot exist serviced separately), and I've put about 15,000 miles on the car without existent result. And then with the proof that at least the the intake manifold valve had effed off to Narnia (or, more realistically, out of the tailpipe at some signal), the decision signal was reached: do I shell out several hundred dollars for the same verbal setup, or practice I make a move that eliminates the most unlikely "trouble-prone nipple" story I've ever had to tell once and for all for under $130?

The internet is a beautiful affair…a few minutes of hunting and I got smacked in the face with CruzeKits.com. A branch-off from the CruzeTalk.com forums, CruzeKits was started past Andrei, who has created two different methods of dealing with this serious issue, and is currently working on a tertiary version. The original V1 kit required the employ of a throttle body spacer plate made by Bad News Racing, but I chose to become with the V2 kit, which uses a stacked T-port connectedness at the brake booster vacuum fitting to route PCV gas back into the system. A few days after placing my club, everything I needed to get the job done, including the additional step-drill flake, was at my door, ready to go. Follow along as we get our Cruze breathing a fleck better:

Oil out of the cap, onto the exhaust manifold and turbocharger. Last fourth dimension I smelled of oil that bad, was the Mirada before the engine rebuild.

But when I say oil went everywhere, I mean information technology. I wasn't sure if that was the only oil leak, just until nosotros could stop the pressurization that was blowing it out of the peak, we wouldn't be able to observe any more trouble spots.

Footstep one: the whorl pack and leads. What I didn't get a photo of was the spark plugs…or the dripping plug socket each time I stuck information technology downwards into the head. Plugs were replaced, terminals were hit with electrode cleaner.

More nastiness plant inside of the intake manifold. Each port had cooked oil of varying degrees inside and were treated to a blasting of carb cleaner to rough out the heavy stuff, followed past quondam shotgun cleaning brushes to fine-sweep the rest. A cracking fox: you can port out the "tumbler" (the wall on the floor of the runner) to choice upwardly a small bit of power if yous so choose. I prefer MPG hither, and then I left them be.

Undeniable proof that the engine was gettin' high on it's own supply: fresh oil around both sides of the throttle body and cooked rest in the butterfly. Plenty of cleaning done here.

At the dorsum of the runner, you can see the spot where an orange or peach-colored condom valve should be. There was no evidence of the remains of the original unit of measurement to be found, so on to fixing the issue…and that doesn't mean putting a new one in here.

Fuel injectors…showed oil show besides at the base. They were cleaned thoroughly, as were the intake ports.

That's the PCV port. Need I say more?

Regardless of whether go for the V1 or V2 kit, yous volition exist playing in some plastic resin, which is shipped equally part of the kit.

Aye, I know, that looks horrifying. Where the big eye opening of the valve used to be is a cocky-tapping screw and a washer, and that's cached under plenty epoxy to guarantee that it won't meet the lite of twenty-four hour period for millennia, far equally I'chiliad concerned. You desire every piffling hole in that port sealed shut.

Next up is drilling out a hole for the new and improved port. For this, take the larger of the ii washers that came in the kit, put it close to the runner opening merely back enough to give you some jerk room, and open a 9/16th hole. I'd suggest drilling a guide hole to brand sure the step drill stays true.

A petty bit of file or sandpaper time hither doesn't hurt. Be sure to take the fourth dimension to accident the shavings out…in my case, a couple hundred PSI from the air compressor did the flim-flam. That might have been overkill, merely any.

The washer and nut demand some quick solitary time with a grinder to fit into the port, merely this is the replacement for the valve. Well, part of it.

The other major role is this pressure bank check valve that is but near radical overkill for what you'll ever need. Thread sealer, tighten things down carefully, and route the new hose up to the modified fitting…

Included in the kit is the additional T-port fitting. Y'all simply stack the new piece onto the original ane and motion forth. Hoses, clamps, fittings, hardware…the only affair you demand to bring to this political party are the hand tools and the grinder.

The hardest role of the entire conversion was one vacuum line that is absolutely buried underneath the left side of the intake manifold. With my big paws, I had to get the intake loose before I could try to disconnect information technology. The plus side to the kit is that it's not as well bad to piece of work on. The most exotic tool you volition need is an East-ten socket, which this engine demands…those funky bolts are everywhere. The examination drive showed that something is now very right with the engine…information technology's peppier than always and doesn't bog on hills where information technology used to. Unfortunately, from the underhood smells, there has to be at least 1 more oil leak somewhere. We'll find information technology sooner or later, just for now. we've at to the lowest degree fixed the root crusade of the problem.
